Arduino automation to control sonic barriers for birds

How to switch on and off sonic barriers for environmental protection of birds with the remote programming of a SCADA system

Arduino PLC for Industrial Control of Sonic Barriers

Every year, thousands of birds are killed by colliding with wind turbine blades; a figure that is expected to rise as wind energy continues to develop.

With the help of an Industrial Shields controller Arduino, bird collisions with wind farm generators can be prevented. With the remote programming of a SCADA system, the automatic switching on and off of sonic bird barriers can be managed to protect the lives of these animals.


According to a study by the  US Fish and Wildlife Service , wind power generation by turbines or wind turbines results in the death of  140,000 to 500,000 birds annually.

Even though the magnitude of the figures must be interpreted, this issue has become an ongoing problem, as seemingly small mortality rates can be fatal for endangered species.

It is therefore important to plan, develop and monitor wind energy projects in order to minimize bird deaths and thus ensure the continuity of the species.

ATS Panama

With the aim of safeguarding bird populations, the company ATS Panama has asked us to improve an already proven sonic barrier design. Our client wanted to control the sonic barriers installed in the wind farm using open source technology: using a single industrial Arduino PLC with the information and recording of the operating hours, ATS Panama wanted to remotely manage the monitoring of the whole process.

Solution with an industrial PLC

The solution suggested by Industrial Shields consists of the installation of the industrial Arduino PLC controller M-DUINO PLC Arduino Ethernet 38AR I/Os Analog / Digital / Relay PLUS. The installation of this PLC for industrial automation provides the customer with an easily integrated solution, since:

  • Using a variety of inputs and outputs, the controller can be easily integrated into an existing system.

  • It is a scalable system and can be expanded without becoming obsolete.

Implementation of automatic switch-on of the sonic barriers


ATS Panama has proceeded to integrate the Industrial Shields PLC in order to manage the automatic switch-on of the barriers according to the schedules established by the environmental authorities. As these schedules vary according to the time of year, the controller has been programmed taking this variable into account.

In addition, the barriers can be switched on remotely from the customer's SCADA system if required, without the need for on-site activation.

In addition, the customer decided to store within a removable μSD memory a log with:

 The operating hours and 

 The most important operating parameters of the implemented system.

Thanks to this application, authorities will be able to audit the proper functioning of the equipment.


Resource optimisation

Resource optimisation

Turbine shutdowns are not necessary because the mortality rate is under control thanks to the sonic bird barriers.
